Abstract: A piston engine having a crankshaft and at least one connecting rod which corotates with the crankshaft, wherein the connecting rod has a small eye and a large eye. The connecting rod has a compression piston, preferably a combustion chamber piston, which is arranged on the connecting rod and can be adjusted eccentrically by means of an eccentric member and an adjusting system, preferably an adjusting linkage. The adjusting system is supported by means of at least one support piston which can be moved in a support cylinder of the connecting rod, wherein the support cylinder and the support piston form a specific leakage path. Oil of the piston engine counteracts a movement of the support piston as damping medium in the support cylinder, wherein the oil can flow along the specific leakage path between the support piston and the support cylinder.

Abstract: The invention relates to a cylinder head (1) of an at least one-cylinder internal combustion engine with direction injection of a motor vehicle with a flame deck (2) and with an oil deck (3). An intermediate deck (4) is situated between the flame deck (2) and the oil deck (3), and at least one injector pipe (5) extends from the flame deck (2) up to the oil deck (3). The intermediate deck (4) joins a lower area of an injector pipe (5), particularly an injector dome (6) that is situated approximately centrally in the area of the flame deck (2). When viewing from the flame deck (2), the intermediate deck (4) extends outward in a concave-like manner so that the intermediate deck (4) joins a lateral wall (7) in a range of 40% to 60% of the distance between the flame deck (2) and the oil deck (3).
